Final answer:
After a myelogram, the patient may be taken to a CT scan while the contrast is still in the subarachnoid space.
Step-by-step explanation:
After a myelogram, the patient may be taken to a CT (Computed Tomography) scan while the contrast is still in the subarachnoid space. CT scans use a series of X-ray images taken from different angles to create cross-sectional images of the body. This imaging modality can provide detailed information about the spinal cord and the surrounding structures.
